The fast breeder reactor "MONJU" (hereafter "MONJU") is equipped with the system called "MONJU Integrated Data Acquisition System (MIDAS)" to effectively acquire, accumulate and analyze relevant real-plant process data gathered from the system start-up test. At present, "MONJU" has been suspended due to a sodium leak accident that occurred in 1995. However, the main part of remodeling construction to prevent sodium leaks was completed in May, 2007 and "MONJU" is highly expected to resume its operations, stepping into the practical testing phase. In this situation, "MIDAS" has been replaced with an upgraded version before the system start-up test was resumed. This paper describes overview of the new "MIDAS" system.

PLANET is a high-pressure neutron beamline recently constructed at MLF in J-PARC. Most characteristic feature of the beamline is to possess the large six-axis multi-anvil high-pressure ATSUHIME press, which enables in-situ neutron diffraction under high pressure and high temperature condition up to 10 GPa and 2000 K. Smaller presses, a Paris-Edinburgh press and Mito cell, are also available and the accessible PT conditions with each device are 20 GPa at room temperature and 5 GPa at 77 K, respectively. The beamline is equipped with incident slits and receiving collimators that eliminates parasitic scattering from the high-pressure cell assembly to obtain clean data. The high performance of the diffractometer and low-parasitic scattering characteristics enables precise structure determination of crystals and liquids under high pressure and temperature conditions. In this presentation, the specification of the PLANET and recent results obtained at PLANET are introduced.
